It is the object of my invention to produce a window sash holder whichmay be attached to the slidable'sashes of windowsand which will permit them to be moved up or down as desired and will retain them. inany desired position without the necessity of having the customary balance weights; A further object of my invention is to include in" such a sashholder a lock which'willprev'ent the opening a of the window from the outside. a i

'I accomplish the'above'objects by mounting in the side ofavwi'ndow sash a roller-supporting member the'rollers of which are spring-.

pressed into engagementfwith the window "casing with sufficient pressure to retain the sash in anydesired position ;@and I provide my sash-holder with a locking device in the form of an eccentric cam which may, when desired, be spring-pressed into engagement with the window-casing to prevent opening of the window, T

The accompanying drawing illustrates my invention F igzf 1 is a fragmenta'l elevation 01 a pair of window sashesand their associated s easing, the sashes being equipped with a device embodyingmy invention; Fig. 2 is a fragmental longitudinal section through the window sash showing details of my device; and Fig. 3 is a fragmental end elevation of 2' tithe window sash showing further details 01 construction. 7

I have shown my invention as applied to the upper sash 10 and the lower sash 11 of a window, both sashes being vertically slidable :in a window casing 12. For simplicity but one end of each sash is shown, as it will be understood that the other end of each sash will correspond to that shown. The vertical end faces of the sashes 10 and 11 are provided with recesses for the reception of my'sash-holder, the various parts of which are supported from a plate 13 which bridges the recesses in each sash and is aflixed to the sash by. suitable screws 14.

' i Passing through the plate 13 is a screw 15 two legs of the channel are rotatably mounted 59 rollers 17 adapted to engage the window casits two limits of movement. Thus, thespring mg 12. Between th m b a hug on the end of the screw 15, I providea com--' pression spring 19 w'hi'c h'acts to hold'the rolL ers 17 firmlyinengagementwith the window casing-12. Preferably, the two ends ofthe spring 19 are bent so as to extend fora short bent ends, the -end20 asshown, engaging a distance parallel tothe screw 15, o'ne'of such f hole in the member 16, and the-other end, the

end 21 as shown, being arranged to engage one face of the nut 18. This arrangement of the spring prevents-rotationof the ,nut 18,and

thus makes itpossible toadjustthe tensionoi',

the spring 19'byrotatingthe screw 15-; r I a, v

Pivotally mounted between twoyears ,25 which extend inwardly from the inner face of the plate113 isja cam-26. Rigid withthe cam 26' is an arm'27 to which is alfixed one I 6 end of a tension spring 28, the other end of which is attached to an arm 29 extending inwardly fromthe plate 13. The cam 26 is provided with a square axial recess3O for the 1 reception of a square -key3l by which'the cam may be rotated either into orout of engagement with the window casingf12Q The arm 2 7is so angularlylocated relative to the center of the eccentric cam 26 that the spring 28 crosses the axis of pivotal mounting of the cam 26 when the cam is rotated between 28 operates to hold the cam firmly in engage ment with the window casing when the cam is in the fulllineposition shown in Fig.2 orto hold it out of engagementwhen in the dotted line position. i i a z "With the cam 26 in the full line position shown,'u pward movement of the sash lliis prevented byreason of thetendency. of the sures that the two rollers 17 will bearwith equal force against the casing 12. v

With the lock-cam 26 disengaged from the casing 12, the sash '11 may be raised or.

lowered as desired. When moved-to the desired position, the friction of the springpressed rollers 17 is sufficient to retain the sash in any location. V

The sash holder provided for the upper sash may be substantially the same as that mounted in the lower sash, but I have illustrated it as slightly modified in order to facilitate adjustment of the spring. In this modification, the plate 13 is provided with a depressed center portion '40 which has a threaded opening for the reception of an adjusting screw 41. A coil spring 42, similar to the spring 19, acts between the head of thescrew 41 and the member 16. A hole 43 is provided leading from the bottom of the reces's in the sash to the inner side of the sash. A screw-driver may be insertedthrough this hole to adjust the tension of the spring42 by rotation of the screw 41 without the necessity for removing the sash from the casing. The

depressed central portion in the plate'13,

' makes possible the projection of the threaded its associated casing, the end face of such sash being provided with a recess, a plate bridging such recess and secured to said sash, a member located in such recess, a screw passing inward through said plate and said member, a nut on the inner end of said screw, rollers rotatably mounted on said member on opposite sides of said screw and adapted to engage said casing, and a (3011 spring surrounding said screw and acting between said nut and said member for forcing said rollers into" engagement with said caslng, the ends of sa1d'- coil spring engaging saidmember and-said nut to prevent" relatlve rotatlon betweenthem.

2. In combination with a window sash and its associated casing, the end face of such sash beingprovided with a recess, a plate bridging such recess and secured to sald' sash, a me nber located in such recess, a screw passlng 1nward through saidplate and said memb'er, ia

nut on the innerrend of said screw, rollers rotatably mounted on said member on oppo-' site sides of said screw and adapted teen: gage said casing, and a coil spring surrounding said screw and acting betweensaid nut and said member for forcing said rollers into engagement with said casing, said screw'be ingloose-ly supported in said plate so that 1t can move angula-rly relatively thereto.

3. A sash holder, comprising a plate, a screw rotatably mounted in said plate, a nut on said screw, a member slidably mounted on said screw, a coil spring surrounding said screw and acting between said nut and said member, and rollers carried by said'member on opposite sides of said screw, said plate being provided with openings for the reception of said rollers,the ends of said coil spring engaging said member and saidnaato' pre vent'relative rotation between them.

4. An inaccessible spring tensioning means comprising an abutment element, a bolt having its shank extending therethrough and forwardly and rearwardly thereof, a spring mounted on said shank'rearwardl-y. of said element; the forward terminal portion of said spring'engaging in sai'd'element to hold the spring from rotation, a nut mounted on said shank=rearwardly of said'sp'ring, and a projection carried'by the rear-end of thespring and engaging thenut to prevent-rotation of the latter relative to the'spring;
